Background technology
Spheric grinding machine is a kind of novel spheric grinding machine.Workpiece can be finished surfacing processing automatically and continuously behind clamped one time, lathe is applicable to the accurate grinding processing of spheroid.
At present, process the method that adopts this bearing with spherical outside surface outer ring two kinds of the mill method of swing and infeeds arranged substantially:
For swinging the mill method, the swing grinding lathe has stronger cutting power, so grinding speed is fast, process time is short.With swinging mill processing spherical bearing outer ring, should guarantee to swing the workpiece centre of sphere and the emery wheel axis is in the same level line, coincide with emery wheel transverse center section again.In the processing, since the vibration at lathe self swinging plane place and the not wide property of workpiece, the very difficult uniformity that guarantees its spheric curvature.
For infeed, in this method for grinding, the spheric curvature of bearing outer ring depends on the shape that emery wheel is trimmed.During grinding, because the surplus of bearing outer ring itself does not wait and shape is different, therefore the shape of intrinsic emery wheel at any time all may be destroyed.This processing method efficient is low, and crushing is frequent, and its spheric curvature also is difficult to guarantee, does not generally adopt.
More than two kinds of grinding methods, though all can process the spherical bearing outer ring, be subjected to the restriction of its grinding method, can't solve and the cooperating of spherical bearing block, more can't fundamentally guarantee the stable qualification rate of spheric curvature.
